Intracardiac Metastases Detected by 18F-FSPG PET/CT.

PET/CT imaging is frequently used for cancer diagnosis and restaging as metabolically active cells, including cancer, utilize glucose for proliferation. F-FDG is the most commonly utilized radiopharmaceutical in PET/CT imaging. Limitations of F-FDG imaging include intense physiologic uptake in benign tissues such as the brain and myocardium.
